I�am a 57 yo female.�i take symbicort for chronic bronchitis that is under control. No flare-ups. Suffer from post nasal drip. For the past week or so, I have�an increased�post nasal drip, clear mucus sometimes sticky but clear. Using a steroid nasal spray for almost 2 weeks now.�feeling like I can't take enough air in,� being out of breath even though my oximeter shows very good oxygen levels.�when taking a deep breath, especially with an open mouth I have noticed, �i get pain, more like irritation,� down my throat or even lower than that.� this causes my to (dry) cough and gives me chills. I can't�even take my symbicort�inhaler properly because I start to cough the second I inhale it and can't hold it in.� � worsen with activity, a little better when lying down.�at times pressure in my left maxillary sinus,� my left nostril gets blocked on and off. Feel like I have mucus. I need to cough up but almost nothing comes out.� in addition I had a low fever (around 37-37. 4c�. I never get a fever, not even with a cold. I am always around 36) but taking paracetamol for 2 days and its back to normal. Muscle pain in my thighs and upper arms. No wheezing. No covid-19, chest x-ray�was ok will appreciate your insight.
